If you review the “disk free” section from the RDA report, the mount point will show as almost full. You can also check this from a df on Linux. The backup will be attempting to write to a larger disk space than is available.
The reason for this error is the there is not enough disk space on the drive to complete the backup.
To resolve this error, clean up unnecessary files on the disk, or add disk space to the disk then re-run the backup.
